The Paradyn Parallel Performance Measurement Tools

by Barton P. Miller, Mark D. Callaghan, Jonathan M. Cargille, Jeffrey K. Hollingsworth, R. Bruce Irvin , Karen L. Karavanic, Krishna Kunchithapadam, Tia Newhall - IEEE COMPUTER , 1995
"... Paradyn is a performance measurement tool for parallel and distributed programs. Paradyn uses several novel technologies so that it scales to long running programs (hours or days) and large (thousand node) systems, and automates much of the search for performance bottlenecks. It can provide precise ..."

A support vector method for multivariate performance measures

by Thorsten Joachims - Proceedings of the 22nd International Conference on Machine Learning , 2005
"... This paper presents a Support Vector Method for optimizing multivariate nonlinear performance measures like the F1score. Taking a multivariate prediction approach, we give an algorithm with which such multivariate SVMs can be trained in polynomial time for large classes of potentially non-linear per ..."

The impact of human resource management practices on turnover, productivity, and corporate financial performance.

by John T Delaney , Mark A Huselid - Academy of Management Journal, , 1995
"... In 590 for-profit and nonprofit firms from the National Organizations Survey, we found positive associations between human resource management (HRM) practices, such as training and staffing selectivity, and perceptual firm performance measures. Results also suggest methodological issues for conside ..."

The performance of mutual funds in the period 1945-1964

by Michael C. Jensen - JOURNAL OF FINANCE , 1968
"... In this paper I derive a risk-adjusted measure of portfolio performance (now known as "Jensen's Alpha") that estimates how much a manager's forecasting ability contributes to the fund's returns. The measure is based on the theory of the pricing of capital assets by Sharpe (1 ..."

Performance of optical flow techniques

by J. L. Barron, D. J. Fleet, S. S. Beauchemin - INTERNATIONAL JOURNAL OF COMPUTER VISION , 1994
"... While different optical flow techniques continue to appear, there has been a lack of quantitative evaluation of existing methods. For a common set of real and synthetic image sequences, we report the results of a number of regularly cited optical flow techniques, including instances of differential, ..."

, matching, energy-based and phase-based methods. Our comparisons are primarily empirical, and concentrate on the accuracy, reliability and density of the velocity measurements; they show that performance can differ significantly among the techniques we implemented.

Exceptional Exporter Performance: Cause, Effect or Both

by Andrew B. Bernard, J. Bradford Jensen - Journal of International Economics , 1999
"... A growing body of empirical work has documented the superior performance characteristics of exporting plants and firms relative to non-exporters. Employment, shipments, wages, productivity and capital intensity are all higher at exporters at any given moment. This paper asks whether good firms becom ..."

become exporters or whether exporting improves firm performance. The evidence is quite clear on one point: good firms become exporters, both growth rates and levels of success measures are higher ex-ante for exporters. The benefits of exporting for the firm are less clear. Employment growth

Tobins Q, corporate diversification and firm performance

by Larry H. P. Lang, René M. Stulz , 1993
"... In this paper, we show that Tobin's q and firm diversification are negatively related. This negative relation holds for different diversification measures and when we control for other known determinants of q. We show further that diversified firms have lower q's than equivalent portfolios ..."

Motivational and self-regulated learning components of classroom academic performance

by Paul R. Pintrich, Elisabeth V. De Groot - Journal of Educational Psychology , 1990
"... A correlational study examined relationships between motivational orientation, self-regulated learning, and classroom academic performance for 173 seventh graders from eight science and seven English classes. A self-report measure of student self-efficacy, intrinsic value, test anxiety, self-regulat ..."

Understanding packet delivery performance in dense wireless sensor networks

by Jerry Zhao , 2003
"... Wireless sensor networks promise fine-grain monitoring in a wide variety of environments. Many of these environments (e.g., indoor environments or habitats) can be harsh for wireless communication. From a networking perspective, the most basic aspect of wireless communication is the packet delivery ..."

In this paper, we report on a systematic medium-scale (up to sixty nodes) measurement of packet delivery in three

Generating Representative Web Workloads for Network and Server Performance Evaluation

by Paul Barford, Mark Crovella , 1997
"... One role for workload generation is as a means for understanding how servers and networks respond to variation in load. This enables management and capacity planning based on current and projected usage. This paper applies a number of observations of Web server usage to create a realistic Web worklo ..."
Abstract - Cited by 944 (11 self) - Add to MetaCart

The tool, called Surge (Scalable URL Reference Generator) generates references matching empirical measurements of 1) server file size distribution; 2) request size distribution; 3) relative file popularity; 4) embedded file
